I have a lenovo x300 with Mint 13/MATE. I upgraded from Mint 10 (clean install) and the scroll feature on the trackpad doesn't work anymore. I've performed a dist-upgrade. It's coming up as a Generic PS2-mouse when I think it should be a Synaptics. I do not have a Touchpad section in my mouse settings. I installed gpointing-device-settings, but it doesn't do anything.

Part of me thinks it's a Gnome 2.6 ---> MATE problem. Any help would be greatly appreciated.

thanks for the reply. I've had the machine out on loan for a few months and haven't been able to address the problem. I was going to upgrade to 14 and see if it solved the problem, but given your report I will hesistate. thanks again.
